This invention relates tograin binders. Grain binders as now standard inthe art include a, main framel carrying an` accessory driving shaftinclined to the vertical, said shaft being appropriately supported inbearings mounted on the elevatorl frame that-leads to the binder deck.This shaft Vcarries a gear that is driven from another gear carried onthe driving elevator roller shaft. In thisV fashion the verticallyinclined shaft is driven and it, in turn, has other connections fordriving the reelfrom its lower end and the butter mechanism onthe binderdeck from its upper end. The gear. on this. inclined shaft, which is,driven from the elevator roller shaft, is subjected toa considerableload resulting in wear that eventually interferes with the properdriving of the related parts. SometimesV these driving and driven gearscannot properly be meshed because of variationsin` the manufacture ofcorrelated parts. The problerlntherefore, is to provide` an adjust-Lmentin the form of a take-.up device that will permit the proper meshingVrelationship between the driving gear on the elevator roller shaft andthe driven gear on the inclined accessory shaft.

Accordingly, it is'l the primary object ofV this invention to yprovide agear adjuster for vthe purposesstated, which will resultin het-V teroperation of the driven accessory parts of the binder. as well aspermit'of more accurate assembly, to compensate for variations inmanufacture.

An embodiment of the invention has been selected by way of example asshown inthe accompanying sheet of drawing, wherein:

Figure l is 'a general perspective view looking from the frontiy of somuch of the grain binderv as is necessary to .illustrate the inventionand the corelated accessory driven parts Figure 2 is a sectional viewthrough the inclined accessory shaft, showing its associ- `ated drivingconnections and the improved gear adjuster mechanism; v

Figures 3 and .4L are respectivelytop and vertical sectional views ofthe spacer nut; and,

Figures 5 and 6 are respectively top and gear adjuster elevationalviews` of the adjusting -Spacerfor quill.Y

Somuch of a. grain binder mainframe as] is necessaryy for thepurpose ofthis disclosure appears. 'at 1'Q, ,the same comprising a gen,- 55 erallyvertically 'disposed member, which carries at its upper endtheconventional bracket;

1l `mounted above the elevator frame, not shown. Thisbracketllvhasconnected; to it in any appropriate manner 'a lower` bearingv 60 l2andan upper bearingl, the twoj bearings mentioned serving asfspacedsupports flor.rv journaling an accessory shaft, l` inclined toythefvertical, as shown n Figure la.. This aC- cessory shaft at its upperend Vcarries a bevel pinion 15j by 'means'of all. elongatedfkeyway andlkey: 1,6 to permit of'slidingly moving the gear 15s axially ofthe shaft14, asgwillflater more fully appear, Y y A The bevel kgear 15-is.drivenf'rom the ,bevel 70 pinion lixed to the front endl of" a ,rollerdrive shaft 18,` that operates the elevatonnot shown, which moves thegrain lto thefbindfer deck, not shown, ,as is wellunderstoodin thisart.V Thus, the shaftlS servesasadrive-shaft. 75. and the accessoryshaftI 14k is driven there.- Y from. l v

The lower endjof theshaft M carriesa bevel, gear 19which drives a bevel.pinion 2,0 on a shaft 21, which leads to andoperates the. reel, so notshown, the shaft 2 l being journaled nan extension of the bearingl2heretoforedescribed, which bearingl2 includes an upright., bifurcatedboss 22, which receives between `its, forks thelug23'ofacup-shapedbearing block 85 24. As the bearing l2 is fixed, thelugand`boss arrangement- 22, 23 servesto hold the cup 24 against rotation in,an Yobvious manner, This cup 24 receives` the hub of a bevel gear 25,whichdrives the-lower elevator` by connections not necessaryhere tobecshowni ,The important point to remember in this regard,

however, is that the gear 2,5, by means` ofapin a lower opening 30, isaxially slid over the CII shaft 14 to rest on the upper edge of the hubof the gear 25. Said cup 29 at its upper edge is provided with aninternally threaded opening 31 to receive a spacer quillor vsleeve v32,:n

which, atits upper end, abuts and serves as a support for the gear 15,while at its lower end said quill is threaded at'33, for a substantialdistance along its lower length, threadedly' to fit into the threadedopening 31 of the cup 29.

The cup is furthermore provided with diametrically opposed pairs ofvertically elongated slots 34and 35, through which is passed a cotterpin 36, said pin valsopassing through an appropriate bore in the shaft14. The upper end of the quill 32 is provided with an enlarged verticalslot 37 to provide a passage registering with the keyway of slot 16, soas not to interfere with the adjustment of the gear 15 and movement ofthe quill 32. Obvioilsly now in practice, when wear results between thegears 17 and 15, the cotter .pin 36 will be removed and, yby means of ahand wrench engageable with a wrench portion 38 on the cup 29, said cupcan be turned, threadedly to move the quill 32 upwardly to push the lgear 15 into proper meshing engagement with the gear 17, whereby to takeup play which has resulted from excessive wear. As a result, the shaft14 and the accessories driven therefrom will be properly driven from thedrive shaft 18. It will beunderstood that, in operation, the nut 29 andquill 32 turn with the shaft 14. After the adjustmenthas been effected,the cotter pin 36 is returned to either of the opposed slots 34 or 35,to lock the parts in their newly set position.

The gear adjuster mechanism just described also proves to be4 veryuseful in the factory assembly of the parts, because any variationsresulting from manufacturecan be compensated for by the means 29, 32 tocause the gears 15 and 17 to be properly set before the machine isshipped from the factory, to insure correct meshing relationship.

From this disclosure, it will be apparent that animp'roved gear adjusterhas been provided for the accessory drive shaft of a grain binder, whichis simple, cheap to produce, and effective in operation, and that suchstructure accomplishes the objects heretofore recited.

' It is the intention to cover any such changes and, modifications ofthe example herein chosen for purposes of illustration which do Vnotdepart from the spirit and scope of the inven j tion as expressedin theappended claims.
